it has disturbed me for two days, i find some question use listView ,
or add drawerView.bringToFront();drawerView.requestLayout();
But nothing changed.
by the way , i used toolbar in a fragment like this
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_main_title,container,false);
mToolbar = (Toolbar)v.findViewById(R.id.main_title_toolbar);
mDrawerLayout = (DrawerLayout) getActivity().findViewById(R.id.drawer_layout);
mToolbar.setTitle("首页");
mToolbar.setTitleTextColor(getResources().getColor(R.color.text));
((AppCompatActivity)getActivity()).setSupportActionBar(mToolbar);
mToolbar.setNavigationIcon(R.drawable.navigation);
setHasOptionsMenu(true);
mToggle = new ActionBarDrawerToggle(getActivity(),mDrawerLayout,mToolbar,
R.string.drawer_open,R.string.drawer_shut){
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
drawerView.bringToFront();
drawerView.requestLayout();
}
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
};
//mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
return v;
}

Oh, i just so a article.it has solved my problem.
here is the link : enter link description here
You just have to bring your drawerLayout to the front,
so try to use these two method
mDrawerLayout.bringToFront();
mDrawerLayout.requestLayout();
then you can find it solved,if you want know more about this,search"Z order".

open and close DrawerLayout null exception

I am trying to add DrawerLayout on my app but the items are not responding to click. I have tried logging the output on the console but nothing show up when the items are clicked. Here is my code
MainActivity
public class DashboardActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
Toolbar toolbar;
DrawerLayout drawerLayout;
NavigationView navigationView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation_drawal);
drawerLayout = (DrawerLayout) findViewById(R.id.drawal_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.open_drawer,R.string.close_drawer);
drawerLayout.addDrawerListener(toggle);
toggle.syncState();
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
int id = item.getItemId();
Log.i("info", String.valueOf(id));
switch (id){
case R.id.dashoard:

I have checked the drawerlayout, menu and the main activity but I can't really figure out what the problem is. Anyone one who can help me.
You forget to call navigationView.setNavigationItemSelectedListener listener that's why navigation item not being called, just add this line
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(this)
Hope it will help you!!

Navigation drawer icon not showing

I'm building Xamarin Android application and I want to implement right navigation drawer with drawer toogle in a custom action bar. Everything is working (drawer slides from right side,...) except one thing: the navigation drawer icon is not showing.
So, this is my Activity.axml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:id="#+id/drawerLayout">
<!-- Main Content -->
<FrameLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:id="#+id/map" />
...
</FrameLayout>
<!-- Right Navigation Drawer -->
<LinearLayout
android:orientation="vertical"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#f2f2f2">
...
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>
And this is my Activity.cs:
using Android.Support.V4.App;
using Android.Support.V4.Widget;
...
public class Activity : Activity
{
...
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToogle;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
ActionBar.SetDisplayShowHomeEnabled(false);
ActionBar.SetDisplayShowTitleEnabled(false);
ActionBar.SetCustomView(Resource.Layout.CustomActionBar);
ActionBar.SetDisplayShowCustomEnabled(true);
SetContentView(Resource.Layout.Activity2);
mDrawerLayout = FindViewById<DrawerLayout>(Resource.Id.drawerLayout);
mDrawerToogle = new ActionBarDrawerToggle(this, mDrawerLayout, Resource.Drawable.ic_drawer,Resource.String.open_drawer_layout, Resource.String.close_drawer_layout);
mDrawerLayout.SetDrawerListener(mDrawerToogle);
ActionBar.SetDisplayHomeAsUpEnabled(true);
ActionBar.SetHomeButtonEnabled(true);
...
}
protected override void OnPostCreate(Bundle savedInstanceState)
{
base.OnPostCreate(savedInstanceState);
mDrawerToogle.SyncState();
}
public override void OnConfigurationChanged(Configuration newConfig)
{
base.OnConfigurationChanged(newConfig);
mDrawerToogle.OnConfigurationChanged(newConfig);
}
public override bool OnOptionsItemSelected(IMenuItem item)
{
if (mDrawerToogle.OnOptionsItemSelected(item))
{
return true;
}
return base.OnOptionsItemSelected(item);
}
...
}
This is my Themes.xml:
<resources>
<style name="CustomActionBarTheme"
parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/ActionBar</item>
</style>
<style name="ActionBar"
parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:height">75dp</item>
<item name="android:background">#00000000</item>
</style>
</resources>
Am I doing something wrong? Any help is appreciated.
UPDATE
My CustomActionBar has app icon and app title. Is this maybe interrupting navigation drawer icon?
This is the solution I have found.
First, you need to add action_bar.xml file with the following content to the menu folder:
<?xml version="1.0" encoding="utf-8" ?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/personalInfoActionBar"
android:title="Informations"
android:icon="#drawable/infoIcon"
android:showAsAction="always"/>
</menu>
Then insert this code in your activity:
public override bool OnOptionsItemSelected(IMenuItem item)
{
if (item.ItemId == Resource.Id.personalInfoActionBar)
{
if (mDrawerLayout.IsDrawerOpen(mRightDrawer))
{
mDrawerLayout.CloseDrawer(mRightDrawer);
}
else
{
mDrawerLayout.OpenDrawer(mRightDrawer);
}
return true;
}
return base.OnOptionsItemSelected(item);
}
Don't forget call actionbarDrawerToggle.syncState()

Drawer layout with two navigation views and selected item colours

I have a drawer layout that needs to have two navigation views in it, because there's a couple of options that need to be aligned on top and another on the bottom, with a divider separating them.
I've managed to make it work, but now I have two different problems with my setup.
1) The first one, I can't change the selected items text color (the background color works as intented via a drawer selector, but for some reason, the selected item's text color is always colorPrimary)
2) The second one is trickier, since there's two navigation views, it can happen that there's a selected row on the first and on the second one, even though they all work loading fragments in the same container. Is there a way to manage that, when an item for the first navigation view is selected, the second navigation view's selected item gets deselected?
This is the drawer's layout:

Thanks in advance!
Solved!
The problem with the color I solved it with a selector, it didn't work before because I had a syntax error (selector tag inside the main selector tag).
This is the color selector's code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#FFFFFFFF" android:state_checked="true" />
<item android:color="#E6000000" android:state_checked="false"/>
</selector>
The second problem I solved it by programmatically deselecting the other navigationview's items onNavigationItemSelected.
This is the function I call:
public void deselectItems(NavigationView view){
int size = view.getMenu().size();
for (int i = 0; i < size; i++) {
view.getMenu().getItem(i).setChecked(false);
}
}
I know there must be a better way to solve the second problem, but this one worked.

Why do my white icons appear slightly darker in the Android Toolbar?

See the screenshot attached. My "Previous" and "Next" icons, whose color code is #FFFFFF, are somwhat darker than the system icons for "Up" and "Overflow".
This is a problem because it leads some users to assume that the buttons are disabled.
My theme on the AppBarLayout is ThemeOverlay.AppCompat.Dark.ActionBar and on the Toolbar is ThemeOverlay.AppCompat.Light, in case that matters. I am using appcompat-v7:23.0.1.
Here's the layout XML ...
<?xml version="1.0" encoding="utf-8"?>

... and the relevant parts of my Activity code.

Here's the XML for the options menu. They are added by a fragment.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/firstButton"
android:icon="#drawable/first_white"
android:title="#string/first_action"
app:showAsAction="ifRoom" />
<item
android:id="#+id/previousButton"
android:icon="#drawable/previous_white"
app:showAsAction="always"
android:title="#string/previous_action" />
<item
android:id="#+id/nextButton"
android:icon="#drawable/next_white"
app:showAsAction="always"
android:title="#string/next_action" />
<item
android:id="#+id/lastButton"
android:icon="#drawable/last_white"
app:showAsAction="ifRoom"
android:title="#string/last_action" />
<item
android:id="#+id/resetButton"
android:icon="#drawable/reset_white"
app:showAsAction="never"
android:title="#string/reset_action" />
</menu>
In your styles.xml add the following attributes to the style to hide the default ActionBar:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
